OVERFLOW AN D WASTE PIPE.

SPECIFICATION forming part of Letters Patent No. 448,842, dated March24, 1891.

Application filed October l 1890. Serial No. 368,174. (No model.)

To all whom it may concern.-

Be it known that I, HENRY F. STowELL, a resident of Rochester, in thecounty of Monroe and State of New York, have invented certain new anduseful Improvements in Overflow and aste Pipes; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

The invention relates to the overflow and waste pipes of wash-bowls,sinks, bath-tubs, and the like, and to strainers for the same, and tomeans for raising and lowering the overpipe, which is adapted to serveas a plug to the waste-pipe.

I-Ieretofore waste-pipes have been provided with strainers which werenot removable, and they have also been combined with overflowpipes thatserved as plugs, and in some cases the strainer has been formed as acontinuation of the overflow-pipe, being fitted within the waste-pipe.These prior constructions are objectionable, for the reason that theyobstruct the waste-pipe and furnish lodgment for organic matter whichdecomposes and develops dangerous bacteria in large numbers, being thefertile source of diphtheria, fevers, and other diseases. So fruitful asource of evil are these deposits that it is highly important to provideoverflow and waste pipes and strainers that are not adapted to lodgesuch matter and that can also be readily cleaned.

By the present improvement both the pipes and the strainer are alwayseasily accessible for cleansing, and these parts are so constructed asto furnish no shelves, nooks, shoulders, or other lodging-places forgrease or other filth which readilyaccumulates upon every projection ina waste-pipe.

The invention consists in the construction hereinafter described andparticularly pointed out.

In the accompanying drawings, Figure 1 1s a broken section of myimproved device applied to awash-bowl. Fig. 2 is a plan of a ring andbail. Fig. 0 is a plan, and fl a side elevation, of a cam-ring. F1g.1s aside elevation, partly in section, of a modification.

Fig. 6 is a side elevation of the strainer and waste-pipe, the latterbeing in part broken away. Fig. 7 is a plan of half a cap or knob formanipulating the overflow-pipe and plug. Fig. 8 is a partial section ofa modification of the lifting device. Fig. 0 is a sectional plan of adetail. Fig. 10 is a partial plan of the slab and basin.

The letter f indicates a wash-basin, and m a slab. S denotes the backotthe wash-stand, and g a bracket secured therein by a nut o.

6 denotes an ornamental sleeve or washer. The outer extremity of thebracket is in the present instance formed with an enlargement or head D.To this is secured a cylinder B, in any suitable manner, in which isfixed a cup-shaped device or cam 0, closing the bottom of the tube andhaving its cylindrical part provided with inclines, as shown in Figs.

1 and 4. 0 indicates a similar device in an inverted position and havingsimilarinclines resting and movable upon the inclines of cup 0'.

A denotes a cap loosely fitting the cylinder B and preferably providedwith a scalloped rim 8. This cap is connected withthe device G by rodsor pins q, fixed to A, but passing loosely through holes in the top ofcup 0.

It will be understood from the above that when the cap A is suitablyturned the in- So clined planes of cam C will ride up those on O, asindicated in Fig. 1.

c c are stops on each cam to prevent too great rotation, and a a arehorizontal faces which provide that the part 0 may rest when 8 5 raisedto its highest point or until its stops 0 c" engage those on C.

The device thus described is adapted to raise and lower an overflow-pipeby means of a rod (Z. The overflow-pipe indicated by a is provided witha downward extension or plug fitted to a seat in the waste-pipe G.

x is an entensionof the overflow-pipe at its top, provided with a bail dhaving a slotted ring-socketr, adapted to receive the rounded 5 foot 19of the rod cl. This rod or bar has a portion 7c, notched or made ofreduced diameter not greater than the width of the slot is in thesocket'1', whereby it can be passed laterally through the slot. Theoverflow-pipe and its bail being then dropped, the rounded foot 1) isreceived in the socket, and a connection similar to a ball-and-socketjoint is thereby provided.

The rod (Z extends up through the bottoms of both of the cams or cups CC, as shown, and above the latter it receives a nut n, beingscrew-threaded at its upper end for this purpose.

It will be obvious that by the before-described operation of turning thecap A and cam C the latter will be raised, also the red (I and theoverflow-pipe. A reverse movement lowers the overflow-pipe and seats theplug at its end in the mouth of the wastepipe. The length or verticalheight of the parts 0 O is such that the extreme upward movement of cupC will not raise the plug If out of the strainer. This prevents largeobjects being carried in the waste-pipe; and, also, the above-describednotch 7.) is located on the bar above the foot 19 a distance about equalto the largest distance which the bar can move to obviate morecompletely the danger of detaching the bar from the bail that exists inthose constructions which employ a simple hook connection.

The strainer 2) is a continuation upward of the waste-pi pe, and has adiameter about equal to the upper end or flared mouth of the wastepipe.It is provided with apertures 71 and e" for the passage of water, theopenings i extending to the top of the waste-pipe to permit the escape,when the overfiow-pipe is raised, of all the water in the basin. Thestrainer is of comparatively large size and surrounds the overflow-pipe.It affords no projections or shoulders within the wastepipe for dirtdeposits, nor does it obstruct the escape of waste-water, and it isalways aceessible for cleaning purposes, as are also both the overflowand waste pipes. The lattercan be readily cleansed by a brush or otherdevice, which can be thrust into the pipe h, secured to pipe G bycoupling y, as far as the usual trap. (Not shown.) In priorconstructions, in which the strainer was attached to the bottom of theoverflow-pipe, it was necessarily made smaller to fit said pipe, and itwas byits location adapted to arrest and hold deposits, therebyinterfering at times with the proper seating of the plug formed on thesame pipe above the strainer. By the present improvement this isremedied, and the choking or partial filling of the waste-pipe and thelodging of dirt is avoided by making the strainer an upward extension ofthe overflow-pipe.

Another evilincident to overflow-pipes having a plug portion near itsbottom and a strainer below is that grease, threads, hair, and othermatters are very liable to lodge in the strainer and also between it andthe waste-pipe and prevent the propel-seating of the plug, whichobjection is entirely obviated by the construction herein set forth.

In Fig. 5 is shown a modification of means for supporting the cylinderwhich holds the elevating devices. T indicates an arm to which thecylinder is secured and provided with a stud or pin 1, fitting asuitable opening in the slab and provided with a screwthreaded endadapted to receive a fasteningnnt Z). S denotes a handle formanipulating the cap A.

In Fig. 8 is represented a modified device for raising theoverflow-pipe. The elevatingbar d is tapped into the rod (i that worksin the cylinder B, and can be screwed up or down to regulate the heightof the bail (Z' and of the overflow-pipe. (his a jam-nut screwedonto theelevating-bar (1 which also serves as a stop for red (Z and determinesits highest position. A is a handle on rod (1", which is jointed to red(Z a distance below the handle equal to that which it is desired toraise the overflowpipe. To effect this operation, the jointed rod ispulled up through the tube B, after which by turning down the handle, asindicated in dotted lines, the rod (1 and the overflow-pipe are alllocked in elevated position. These parts and the strainer are soproportioned that the foot of the overflow shall not be raised entirelyabove the strainer. This handle has a diameter greater than the internaldiameter of tube 3, whereby it constitutes a stop to limit the descentof the jointed rods. The weight of the handle is also snfiicient tocause the section (1 to act as a stop when the rod CZ iS raised to itshighest position, and the said section is turned to a horizontalposition, as indicated in dotted lines in Fig. 8.

As shown in Fig. 8, the notched part L is nearer the joint than abovedescribed, and variation in this respect and also in regard to otherdetails maybe made without departure from the main invention, providedthe principles of construction and operation are not substantiallychanged. In said Fig. 9 the bar (Z is represented as fitting the socketr loosely. This prevents the binding of the parts and provides forsuflicient lateral motion in the overflow-pipe and plug to permit thelatter to be always squarely seated. It also facilitates the separationof the elevating-bar and the overflow-pipe by permitting the latter andits socketed bail to be independently and easily raised sutficientlyhigh to allow the bail to be moved sidewise from the bar at at thenotched part is. It is an important feature that these parts can beseparated readily and in an obvious manner, because ignorant servantswill otherwise fail to properly cleanse the pipes, as happens in someprior devices, wherein the removal of the overflow-pipe is moredifficult.

The present improvement both obviates the danger of accidentaldisconnection, such as occurs where a simple hook is employed, and atthe same time it provides a very obvious and easily-operated mode ofseparation.

The cylinder B, as shown in Fig. 9, is provided with a horizontal arm T,having a stud or pin Z secured tothe slab m. The bracketarm need notrest on the slab, however, nor be connected to the bottom of eithercylinder 13 or B, but can be attached above the bottom of the cylinder,as in Fig. 1, and, if desired, the pin loan be suitably lengthened forthe purpose.

To prevent the cap A (see Fig. 1) from being pulled off the cylinder byinadvertcnce, it may be connected withit bymeans of L-shaped slots inone made to receive pins fast on the other. A A indicate pins, and A A(see Figs, 1 and 9) denote slots, for this purpose; This or like meansfor preventing the accidental displacement of the cap vertically mayalso be employed, if desired, with the form shown in Fig. 5.,

Preferably the basin is provided with a recess for the overflow-pipe, asindicated by dotted lines in Fig. 10, and the covering-slab m issimilarly recessed, the bracketT being made long enough to extend to theslab.

In Fig. 10 the bracket and devices pendent therefrom are broken away toshow the mouth of the waste-pipe. The construction permits theintroduction of a brush into said pipe in a direct line and facilitatesits proper cleansing, it being practicable to push the brush down to thewater-seal.

Having thus described my invention, what I desire to secure by LettersPatent is 1. In combination with a wash-basin or like receptacle, awaste pipe provided with a strainer secured to its upper end, anoverflow-pipe having its bottom fitted to the interior of the waste-pipebelow the strainer, said strainer being located above the bottom of thebasin and outside the foot of the overflow-pipe, and devices for raisingthe said overflow, substantially as set forth.

2. In combination with a wash-basin or like receptacle, a waste-pipeprovided with a strainer secured to its upper end, an overflow-pipehaving its bottom fitted to the interior of the waste-pipe below thestrainer, said strainer being located above the bottom of the basin andoutside the foot of the overflow-pipe, and devices for raising the saidover flow-pipe, said devices being provided with a stop to preventraising the foot of the overflow above the strainer, substantially asset forth.

3. The combination, with a wash-basin or like receptacle, of awaste-pipe, an overflowpipehaving its lower part fitted to a seat in thewaste-pipe, a bail attached to the overflow-pipe and provided at itshighest part with a slotted socket forming a part of the bail, a barhaving an enlarged and rounded head with a diameter greater than thewidth of the slot in the socket and having above said head anotched'part with a diameter less than that of said slot, saidoverflow-pipe being movable vertically on the bar and independentlythereof, and devices for raising and lowering the bar, substantially asset forth.

4:. In combination with a wash-basin or like receptacle, anoverflow-pipe, an elevating-rod made in jointed sections and looselyconnected to said pipe, a cylindrical tube adapted to receive said rod,and a support for the said tube, the upper rod-section above the tubebeing enlarged, whereby it forms a stop, substantially as set forth.
